球磨机运转率反映了球磨机技术状态，它的高低在很大程度上反映生产管理水平，提高球磨机运转率也就提高了磨矿工段的生产能力。针对磨一工段球磨机运转率偏低，运用全面质量管理小组的方法，解决了生产过程中存在的一些实际问题，取得了比较好的效果。 Ball mill operating rate reflects the state of the ball mill technology, its level to a large extent reflect the level of production management, improve the operation rate of the ball mill also increased the capacity of the grinding section. In view of the low operating rate of the ball mill in the first grinding stage and the application of a total quality management team, some practical problems in the production process have been solved and good results have been achieved.
